OCC.Core.IntCurvesFace module

IntCurvesFace module, see official documentation at https://www.opencascade.com/doc/occt-7.4.0/refman/html/package_intcurvesface.html

class IntCurvesFace_Intersector(*args)

Bases: object

• Load a Face. //! The Tolerance <Tol> is used to determine if the first point of the segment is near the face. In that case, the parameter of the intersection point on the line can be a negative value (greater than -Tol). If aRestr = true UV bounding box of face is used to restrict it’s underlined surface, otherwise surface is not restricted. If UseBToler = false then the 2d-point of intersection is classified with null-tolerance (relative to face); otherwise it’s using maximium between input tolerance(aTol) and tolerances of face bounds (edges).
